MAGAZINE-FIREARM.

Specification of Letters Patent.

Patented Nov. 23, 1909.

To all whom it may concern:

Be it known that I, HALE XV. DE Janxxr'r, a citizen of the United States, residing at Centralia, in thecounty of Boone and State of "Missouri, have invented certain new and useful Improvements in l\lagazine-Firearnis,

' of which the following is a specification.

My invention. relates to repeating firearms, and particularly to improvements in the cartridge cut-off mechanism for the magazine. That type of repeating firearm to which my invention relates includes a tu bular magazine arranged parallel with and adjacent to the barrel and opening rearwardly into the receiver.

The object of the invention is to provide simple and effective mechanism whereby the user may at any time readily release all of the cartridges in the magazine to permit the latter to be completely emptied.

That type of magazine firearm with which my improvement is illustrated herein is fully set forth and described in United States Detters Patent No; 528,905 of November 6, 189st; No. 560,032 of May 12, 1896, and No. 776,322 of November 29, 1904. Since the ac tion mechanism employed is set forth in detail in the above referred to patents, it will be unnecessary for me but to generally referto the same herein, particularly as it is not absolutely essential to the present invention that that construction alone be employed in connection with my improved cutoff apparatus.

In the accompanying drawings Figure l is a side elevation on a reduced scale and partly in section of a magazine firearm containing my invention, the ends of said firearm being broken away. Fig. 2 is a relatively enlarged cross section on the line a?w Fig. 1. Fig. 3 is a fragmentary view of. the insideof one wall of the receiver, showing 'the cut-off. Fig. t is a section on the line jl/g/ of Fig. 3, looking up. Fig. 5 1s a sec-' tion on the line z2 Fig. 3, looking up. Fig. 6 is a side elevation of the breech portion of a gun, showing fragments of the barrel ma azine and stock, one sideof the receiver eing partly broken away and the locking bolt being removed. Fig. 7 is a fragmentary view of a partof the receiver, showing the breech-block and locking bolt in section, in the position in which the lockin bolt appears just before the breech is locked Fig. 8 is a perspective view of the locking bolt. Fig. 9 is a view similar to Fig. 6, but showing the breech mechanism fully open. Fig. 10 is a side elevation of the carrier. Fig. 11 is' an end elevation of the breechblock shown in Fig. '8.

1n the drawings, l'is the breech frame or receiver, '2 is the stock, 3 is the barrel and i is the magazine, the latter being arranged underneath the barrel and opening rearwardly into the receiver.

5 is a reciprocating breech-block guided in the frame 1 and actuated to and fro by suitable mechanisni, such as the handle (3, which slides to and fro on the magazine. In the particular form of construction herein shown, which, as already stated, is merely preferable,'this action handle 6 has a rod 7 extending lefll'Vfllfdly and entering the receiver, said rod being connected with a locking bolt 8 in the manner set forth in the above referred to patents. The locking bolt 8 is pivoted at 9 in the breech-block 5 and.

has a tilting action.

\Vhen. the locking bolt is in theposition shown in solid lines Fig. 7, the breech-block is unlocked and may be moved to and fro. lV hen, however, the locking bolt is tilted into the position indicated in dotted lines Fig. 7, it engages the receiver frame 1 at itsrear end and the breech-block 5 at its forward end, locking the same in a forward position. 8 is a lag depending from the forward end of the locking bolt, with which the action rod 7 is directly connected. he first movement of the action rod in a rearward direction operates, through the lug 8 to tilt the locking bolt from its locking position (dotted lines Fig. 7 to the unlocked position (solid lines Fig. 7), and hence the last movement of the action rod in a forward direction\ is to tilt the locking holtinto the position illustrated in dotted lines Fi 7. It is the tilting movement of the 100 mg bolt and lug 8, as will hereinafter be seen, that is availed of for the purpose of mechanically operating the cut-off,-1n the preferred form of my invention. 10 is a tilt ing carrier operating in synchronism with the balance of the actionmechanism, whereby at the proper time it will descend-and rweive a cartridge from the magazine and convey it up to the pro of the retracted breecher position in front lock, whereby when 4 indicated in Fig. 7,

.known and more fully ically operated during manually operated :this part, as well as part 12, now bein the latter advances said cartridge will be pushed into the barrel.

The parts thus far described are parts well described in the above referredto patents.

My implroved cut-off comprises a two-part device w ich is capable of mechanical or manual operation, said cut-off being mechanthe regular. mani ulation of the action mechanism of the rearm to release the cartridges separately and .successively from the magazine to permit them to be fed by the carrier. If at any time it is desired to release all of the cartridges from the magazine, the ;cutoff may be for that purpose. In the particular form shown, the cut-ofl comprises the two pieces or dogs 11 and 12 arranged side by side in a recess in the inner side wall of the receiver and pivoted upon a suitable bearing 01' pin let. The forward end of the cut-oif piece 11 stands slightly in advanceof the forward end of the cut-off piece 12, and first engages each cartridge in the magazine. This piece 11 has a cam face or incline 11, which flares upwardly and in-.

wardly relativelyto the receiver. The piece 12 has acam face or incline 12, which flares downwardly and inwardly relatively to the receiver. The shoulder 15 on the lug 8* of the locking bolt stands between these two inclines when the parts are in the position in whlch position, as before explained, the

the. last advance movement of the action rod 7. If it may be assumed a cartridge in the magazine is now bearing against the forward end of the part 11 (the forward end of the forward end of the held out under the influence of suitab e springs indicated at 1l"-12", Figs. 4 and 5) it will be seen that when the locking bolt is tilted to the looking position (dotted lines Fig. 7), the part 15 on the lug 8 will encounter the incline 11" and press back the; forward end of the part 11, thus permitting the cartrid 'e in the magazine to move rearwardly sli htly where it will be held by encountering die forward end of the part 12 of the cut-off, which'now stands advanced. In this position the cartridge will remain until the part 12 is tilted.

16 is a finger-piece or button mounted in the side of the receiver for manual manipulation. This finger-piece bears against the rear end of the dog 12, whereby the operator may manually tilt said part 12 by merely pressin on the button or finger-piece 16. This tiltin of the part 12 retracts the forlocked and closed the part 11 is 're 'resse I by the action mechanism, it follows t at the cartridges in the magazine may freely escape w enever the button 16 is pressed in.

breech is closed, but. the locking bolt has not yet been tilted by By this means the operator may at any time readily empty the magazine without the necessity of pumping the cartridges successively through the entire action, as was formerly the case. The forward end of the carrier moves in an are slightly to the rear of the forward end of the part 12, so that in the regular operation of the gun in which the cartridges are to be fed successively to the barrel, the operation is as follows: The

against the forward end of t e part 11.

and permits said cartridge to move back against the end of the part '12. The unlocking of the gun frees the part 11, which then presses against the rim ofthe cartridge resting on stop part- 12. i. s the lug 8 descends during the unlocking movement to release the forward end of the part 11, it simultaneously engages the. incline 12' and depresses the same sufiieiently to let the cartridge engaged thereby move back slightly until it encounters carrier (which descends slightly with the lug), against which itis held until the carrier fully descends to permit said cartridge to slide back thereon to be elevated thereby into a position'in front of the breech-block. As soon as the rim of this particular cartridge has moved back from engagement with the forward end of the dog 11, the, latter of course springs'forward under influence of spring 11 so as to engage the next succeed: ing cartridge indie magazine. It will thus be seen that each cartridge ppsilions durin each cy cleof movement of the action mechanism before it is entirely free to move back into a position on top of thecarrier. a

From the foregoing it is ap arent that the cut-elf is operated mechanical y during each 'cycle'of operation of the action mechanism,

after a days shooting."-
